XR (Extended Range) gives the greatest wireless distance. This feature is available on selected NETGEAR routers and adapters starting September, 2004.

• XR greatly improves error correction, and is less vulnerable to noise.

• XR allows very weak signals before disconnecting. NETGEAR equipment trades distance for throughput: the longer the distance, the lower the throughput. Without XR, connections with weak signal strength are dropped. With XR, those connections can be maintained — at even lower throughput. This may be fine for applications such as email. It also makes it easier to troubleshoot in places where non-XR equipment can't connect at all.

NETGEAR Products Supporting XR

• The new WGU624 router ships with XR.
• The new WG511U adapter ships with XR.
• The WGT624 router will have a firmware upgrade to support XR in the September timeframe.
• The WGT634U router will have a firmware upgrade in the October timeframe.
• WG511T, WAG511, WAG311, and WG311T will have firmware upgrades.

Depending on the mode selected, XR is automatically turned on. The adapters connect passively connect to an XR-enabled router. No configuration is needed.

XR clients such as the WG511U adapter can be used instead with non-XR equipment, if you like.
